Specification of Letters Patent. Patented Nov. 24, 1914.

Application filed December 5, 1913. Serial No. 804,895.

To all whom it may concern Be it known that I, EUGENE FIEVET, Fils, a citizen of the French Republic, residing at 24 Rue des Vieux Remparts, Dunkirk, in the Department of Nord, France, have invented a new and useful Improvement in carding-Machines, of which the following is a specification. 1

This application relates to further improvements in the machine described in my prior patent application in the United States made on the 26thday of May, 1913, Serial No. 7 7 0017 whereby the construction'of the apparatus described is simplified and its operation improved. 1

These improvements which comprise the substitution of an oscillatory sifting grating for the screening devices hitherto employed combined with certain modifications of the carding roller system have for their object to increase the eiiiciency and quickness of working of the machine. They are represented diagrammatically in the accompanying drawing as follows Figure 1 shows an elevation of the improved carding mechanism. Fig. 2 shows a plan view of the improved grating. Figs. 3 and 4: show the separate bars of the said grating. Fig. 5 shows another construction of the carding mechanism.

Referring to Fig. 1 of the present drawing, this corresponds to Fig. 1 of the prior patent and shows how the two screens and the receptacle which are placed beneath the cylinder 1 in the previous construction are replaced in the present construction by a grating of the construction shown which fulfils the same purpose. This grating shown in side elevation in Fig. 1 and in plan view in Fig. 2 is composed of bars 3 and 1 (Figs. 3 and 4) of a suitable number clamped one against the other by means of clamping bolts 5 and 6 fixed at their ends.

The bars 3 which form the grating properly so-called and which are shown particularly in Fig. 4 are reinforced at their ends so that being gripped one against the other as stated above, they possess between themselves throughout their length suilicient interstices to allow the escape of the impurities.

The bars 4 represented in detail in Fig. 3 are those which are placed at the ends of the grating and as may be seen they are extended at their lower part by means of the part 7 in which there is pierced a hole 8 to allow of the supporting of the grating 2 upon a shaft 9, the screws 19 serving to fix the same grating upon the said shaft9. As the grating has a certain length which corresponds to the width of the carding roller it is necessary in order to prevent it bending to place at suitable distances apart a bar of the shape 1 in place of a bar of the shape 3. The grating 2 thus constructed receives a continuous oscillating motion so as to shakeand cause to fall the impurities which are constantly being deposited by the carding organs during the working of the machine. This oscillating motion is obtained by means of an eccentric 10 which by means of the rod 11 actuates the crank 12 fixed upon the shaft 9- 0f the grating. I

The sheet iron plates 13, 14, 15, 16 placed underneath the carding organs and suitably inclined serve to guide the refuse and impurities which fall beneath the carding machine so that they are collected upon the ends of the grating, that is to say, upon the ends of the bars in order that they may be shaken and in this manner the impurities will be separated and fall out. The purified refuse however remains upon the grating and slides upon it approaching gradually to the cylinder 1. It is then finally seized by the said cylinder 1 which is suitably coated with pins or teeth and thus re turned to the carding mechanism. Moreover, it is obvious that in practice and according to circumstances, the single barred grating which has been above described might be replaced by two or more oscillating screens of similar construction but less size, which it would sufiice to combine with re-collecting cylinders such as that marked 1 as set forth according to this invention; it is also obvious that it would be possible to substitute for the re-collecting mechanism indicated in Fig. 1, formed of a re-collecting cylinder 1 and of the auxiliary or cleaning roller 17 by the arrangement shown in Fig. 5 which possesses only one cylinder 18 of suflicient diameter and suitably coated with pins or teeth which performs the function of cleaning and restoring, whereby the said result is obtained.

What I claim is:

1. In combination in a machine for carding the tow of textile fibers, a large carding roller, a plurality of auxiliary carding rollers in operative contact with the large carding roller, a barred receptacle beneath the large carding roller adapted to receive the impurities and fibers rejected by the said auxiliary rollers, means for picking up and restoring to the carding rollers such fibers, a rocking shaft adapted to support and 0s cillate said barred receptacle, and crank mechanism operatively connected to said shaft.

2. In combination in a machine for carding the tow of textile fibers, a large carding roller, a plurality of auxiliary carding rollers inoperative contact with the large carding roller, a barred receptacle beneath the large carding roller adapted to receive the impurities and fibers rejected by the said auxiliary rollers, means for picking up and restoring to the carding rollers such fibers, a rockin shaft adapted to support and 0s cillate said barred receptacle, a set-screw adapted to secure the barred receptacle adjustably upon the rocking shaft and mechanism adapted to convey oscillatory motion to the said rocking shaft.

3. In combination in. a machine for carding the tow of textile fibers a large carding roller, a plurality of auxiliary carding rollers in operative contact with the large carding roller, a barred receptacle beneath the large carding roller-adapted to receive the impurities and fibers re ected by the said auxiliary rollers, a grating in said receptacle comprising a plurality of bars each having ends wider than the intermediate part and a downwardly projecting perforated extension at the middle, rollers for picking up and restoring to the carding rollers such fibers, a rocking shaft adapted to support and oscillate said barred receptacle and crank mechanism operatively connected to said shaft.

In testimony whereof I have signed my name to the specification in the presence of two subscribin witnesses.
